Patented Dec. 9, 1930 UNITED, STATES HENRY A. INGAIJLS, OF BAKERSFIELD, CALIFORNIA noAn-sunrncme MACHINE Application filed March 26, 1929. Serial No. 350,020.

My invention relates to road surfacing or leveling machines and its principal object is to provide a machine of this character wherein the road surface will be effectively scarificd and leveled in the same operation. 7

Another object of the invention is to provide a road leveler that will operate on the same principle as a long carpenters jack plane and is operable by one man.

The invention further provides a portable frame having rows of intersecting teeth or blades which act to scarify or cut the ground as the frame is drawn thereover.

The invention also contemplates a vertically adjustable ground leveling bar which is arranged rearwardly of the scarifying elements at the longitudinal center of the frame so as to level the road surface in the path of the scarifying elements.

\Vith the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangements of parts and operations to be hereinafter more fully described, claimed and illustrated in theacable frame composed of parallel runners or side members 5, transverse end bars 6 and bolts 7 passing transversely through the runners, is provided. Metallic shoes extend along the under faces of the runners 5 andare suitably secured thereto.

Arranged between the runners adjacent the forward ends thereof is a pair of intersecting diagonal angle bars 10. The ends of the angle bars terminate in lateral extensions 11 which lie parallel to. and are secured to the runners 5 by transverse fastenings 12. In

order to permit the angle bars to be ar ranged in intersecting relatlon one of them 'rectly in advance of the bar.

served that when loosened dirt and rock tends the other angle bar by fastenings 14L.

Passing through the horizontal flanges of theangle irons is'a plurality of scarifying elements 15 having angularly disposed cutting blades 16. To hold these scarifying ele-- ments in position, U-shaped bolts 17 are provided, each of which embraces one of the scarifying elements and passes through the vertical flanges of the angle bars. For the purpose of leveling the road surface after the same has been cut or scarified a relatively heavy ground engaging leveling bar 18 extends tranversely of the frame rearwardly of the scarifying elements. This bar is rectangular in cross section so as to present a wide road engaging surface. v To hold this screws 20 are vertically adjustable through vertically threaded bores 21in a horizontal cross member 210/, supported from the run- 'ners. The lower ends of these screws are swivelly connected with the bar as indicated at 22.

In order to prevent dirt androck from banking up infront of the bar and hence offering too great a resistance to the path of ,is made .in sections 13 which are secured to bar in-position to permit it to be adjusted I movement of the frame, elongated discharge openings 22 are provided in the runners di- It will be obto bank up in front of the bar it is caused to pass laterally through the openings 22 and discharge at opposite sidesof the frame.

WVhat is claimed is:

In a machine of the character described,v a-

frame to be drawn over the ground and having parallel side members, a Vertically adjustable leveling bar situated transversely of said side members, and guide Walls fixed to said side members for engagement with said adjustable ground leveling bar, the Walls engaging one side of said adjustable ground leveling bar terminating in spa'eedrelation to' the base of said side members for permitting engagement of the dirt with said leveling bar, and said side members having apertures positioned below said last named walls for the passage of dirt therethr ough. a
